The MGA-1000 series of graphite furnace atomic absorption spectrometers crystallizes intuitive technology and exceptional handling.
The unique High Frequency Zeeman background correction system ensures effective compensation of intense and rapidly changing spectral interferences and brings routine analysis of complex samples to new heights. Key technologies - Zeeman High Frequency Polarization Modulation (ZHFPM) background correction
- Simultaneous measurement of total and background absorptions provides accurate background correction even for complex sample matrices
- High intensity electrodeless discharge lamps (EDL) ensure lower detection limits compared to traditional hollow cathode lamps (HCL) and make possible direct As and Se determination at ppb and sub-ppb levels without hydride generation technique
- The stabilized temperature platform furnace (STPF) concept realized
- Instrument drifts arising from various sources e.g. spectral lamps, electronics, are effectively compensated by quasi-double beam optical system. No warm-up needed
- Cold Vapor / Hydride Generation technique available
- Noiseless operation and small size
